Changes in the docs were merged manually and updated to correctly
describe the 2.x layout.
Modify the executor to access the loopback object via `app.loopback`.
Fall back to `require('loopback')` only when `app.loopback` is not set
(loopback versions before 1.9).
The new loopback project layout adds a concept of components like
'rest server' and 'isomorphic client', each component having its own set
of boot files. The name `app.json` is confusing, since it is configuring
a component, not the app (which is the whole project).
In the first phase, all models are defined.
In the second phase, models are configured, attached to data-sources
and exposed on the app object.
This way when the `attached` Model event is emitted, all models are
already defined and thus a listener can get reference of any other
model used in the app.
Rework the way how models are configured, the goal is to allow
loopback-boot to automatically determine the correct order
of the model definitions to ensure base models are defined
before they are extended.
1. The model .js file no longer creates the model, it exports
a config function instead:
```js
module.exports = function(Car, Base) {
// Car is the model constructor
// Base is the parent model (e.g. loopback.PersistedModel)
Car.prototype.honk = function(duration, cb) {
// make some noise for `duration` seconds
cb();
};
};
```
2. The model is created by loopback-boot from model .json file.
The .js file must have the same base file name.
3. The `boot()` function has a new parameter `modelSources` to
specify the list of directories where to look for model definitions.
The parameter defaults to `['./models']`.
As a side effect, only models configured in `models.json` and their
base clases are defined. This should keep the size of the browserified
bundle small, because unused models are not included.
Breaking change.
The bootstrapper no longer calls `loopback.autoAttach`. Applications
have to explicitly configure datasources for their models
via `models.json`.
Breaking change.
In the new 2.x project layout, definition of loopback Models is out of
scope of the boot process. The bootstrapper only configures existing
models - attaches them to a dataSource and the app object.
Hide `compile` and `execute` and provide a better API for browserified
applications:
- `boot.compileToBrowserify(options, bundler)` calls `compile` under
the hood and adds all instructions and scripts to the bundler.
- `bootBrowserApp(app)` is exported by loopback-boot when the module
is loaded in a browser, the function loads the instructions as
bundled by `compileToBrowserify`.
This new API hides all implementation details from the user and makes
it easy to add loopback-boot to any build script.
Split bootLoopBackApp into two steps:
- compile
- execute
Most of the changes are just shuffling the existing code around.
What has changed:
- `loopback.autoAttach()` is called after `models/*` are required.
The calls were made in the opposite order before this commit.
Modify loading of `appConfig` and `dataSourceConfig` to look for
the following files:
- app.json
- app.local.{js|json}
- app.{$env}.{js|json}
- datasources.json
- datasources.local.{js|json}
- datasources.{$env}.{js|json}
where $env is the value of `app.get('env')`, which usually defaults
to `process.env.NODE_ENV`.
The values in the additional files are applied to the config object,
overwritting any existing values. The new values must be value types
like String or Number; Object and Array are not supported.
Additional datasource config files cannot define new datasources,
only modify existing ones.
The commit includes refactoring of the config-loading code into
a standalone file.
